I have an '88 GL1500 with a Motor Trike conversion. It has the Ford rearend with drum brakes. On our trip to Key West we ran into a rain storm. My rear brakes got wet and as drum brakes do, they basically quit working until they dried out. Motor Trike says the master cylinder on this bike can not support disc brakes. Does anyone know of any modifications that will allow me to put disc brakes on my trike or do I just have to live with it?
